Correct Answer: C

Rationale: Flaring of the nostrils is a sign of increased respiratory effort, which is common in clients with COPD experiencing dyspnea. Choices A, B, and D are incorrect. A decreased respiratory rate is not expected in a client with COPD experiencing dyspnea, as they often have an increased respiratory rate. Flushing of the skin is not a typical finding associated with COPD or dyspnea. While a productive cough can be seen in COPD, it is not specifically related to the increased respiratory effort seen with dyspnea.

Correct Answer: B

Rationale: The correct answer is to discontinue the infusion (Choice B) as the signs described suggest phlebitis, an inflammation of the vein. Increasing the IV flow rate (Choice A) can exacerbate the condition by increasing the irritation. Elevating the limb (Choice C) and applying a cold compress (Choice D) are not the appropriate interventions for phlebitis. Elevation and cold therapy are more suitable for conditions like swelling or inflammation, but in this case, discontinuing the infusion is the priority to prevent further complications.

Correct Answer: B

Rationale: The correct answer is B. When instructing a client on the use of a cane, it is essential to ensure that the cane has a rubber tip. This rubber tip helps prevent slipping, providing additional stability and safety. Option A, holding the cane on the weaker side, is incorrect as the cane should be held on the stronger side to provide better balance and support. Option C, keeping the cane on the dominant side, is also incorrect because the cane should be held on the stronger side. Option D, using the cane only on stairs, is not comprehensive as the cane can be used for support and balance while walking on level ground as well.

Correct Answer: B

Rationale: Inspecting feet daily for injuries is crucial for clients with diabetes to prevent unnoticed wounds from becoming infected. This instruction is the most important as it helps in early detection and management of foot problems. Choice A is incorrect because applying lotion between the toes can lead to excessive moisture, increasing the risk of fungal infections. Choice C is wrong as wearing shoes indoors can also lead to foot issues. Choice D is incorrect because cutting toenails in a rounded shape can result in ingrown toenails, posing a risk for infection.

Correct Answer: C

Rationale: After administering a narcotic medication, any unused portion should be discarded with another nurse as a witness. This procedure ensures proper disposal of controlled substances and prevents misuse or diversion. Storing it for later use (Choice B) is not appropriate due to safety concerns and legal regulations. Returning it to the pharmacy (Choice D) is also not recommended as the medication is already out of the pharmacy's control. Documenting the amount wasted (Choice A) is important for accurate record-keeping but does not address the immediate need for safe disposal of the unused narcotic medication.
